Abstract (en)
[origin: EP3699395A1] An assembly for monitoring particulate in a production fluid. The assembly supports routing of production fluid through a restriction and to a strategically located detector downstream and adjacent the restriction. Further, the detector incorporates acoustic attenuating features to provide a tailored detection focused on acoustics directly from particulate in the fluid. These features may include the use of a transducer housing with a ribbed profile to achieve the attenuation. Although, other types of attenuating techniques may be employed.
